The scorer

Check a food

Type a food name or scan its barcode. You get the GSF score right here.

GSF score = net carbs + (2 × saturated fat) + (4 × trans fat), scored on a realistic portion (the label serving, kept between 30g and 100g). Net carbs subtract fiber and the sugar alcohols that don't spike. Lower is better. 0–6 green, 7–12 yellow, 13+ red. How the score works.
